NEW WOOD FIBRE CONE
Optimised with a new wood fibre-structured cone. The 5¼” low loss woofer used in the OBERON ON-WALL has been optimised with a new wood fibre structured cone dedicated to reproducing the delicate midrange and bass frequency area. Constructed from a blend of fine-grain paper pulp reinforced with wood fibres, the woofer has a stiff, yet lightweight structure. And when combined with the low loss surround and spider suspension, the OBERON ON-WALL woofer reproduces the most minute details in the signal, unfiltered and with high accuracy.
REDUCING DISTORTION
DALI’s patented SMC (Soft Magnetic Compound). The use of SMC (Soft Magnetic Compound) in the OBERON ON-WALL greatly reduces mechanical distortion caused by hysteresis and eddy currents. The result is a magnet motor system with a drastic reduction in third-order distortion, which allows the OBERON ON-WALL to deliver extended listening pleasure, a relaxed midrange and a surprising amount of detailing in its class.
OVERSIZED SOFT DOME
Combining well-proven technologies with new features. The oversized 29 mm ultra-lightweight soft dome tweeter was specifically developed for the OBERON series, combining well-proven technologies from our existing DALI ranges with new features. The large size of the membrane lets the tweeter generate higher sound pressure with less excursion, keeping the voice-coil motion to a controlled minimum. The tweeter front plate near the dome has been designed with similar geometry to the OPTICON and RUBICON tweeters to create the optimal working conditions for the soft dome. This results in extended frequency response, wide dispersion and low colouration.
OPTIMISED CABINET
A rigid structure that practically eliminates resonance. The OBERON ON-WALL cabinet is constructed from a high density, CNC machined MDF board dressed in high-grade vinyl. The extremely rigid structure is achieved with solid bracings across the inside of the cabinet, which practically eliminates cabinet resonance. To optimise the timing, the speaker is fitted with acoustic damping material internally along the sides, top and bottom. This creates a more direct contact between the woofer and bass port, which delivers more precise bass and increased midrange attack.
UNIQUE BASS PORT
Making use of the wall to extend bass performance. With its unique bass port design, the OBERON ON-WALL takes things to a whole new level. Originally introduced in the DALI RUBICON LCR, the OBERON ON-WALL bass ports fire downwards, allowing the ports and the wall to work together to extend the bass reproduction far beyond what would otherwise be possible from such a compact cabinet.
